So you were rude, and you do not care, I think that was covered already. Fortunately you can blame raging hormones, so you will probably be fine in the long run. Let me share my story with you, because this same thing happened to me.
I was pregnant and very ready to do everything perfect. I was going to be the perfect mother..... so naturally I would breastfeed, that was without question, and I had looked in to the diapersituation. Where I live, there is a service that you can subscribe to that will deliver clean cloth diapers, and pick up dirty ones, every week, for a fee. This fee was not much above what you would spend on disposable diapers, so, like you, I chose the cloth service, and was ridiculed by all: my DM, my MIL, DH... all of them....but I still went ahead and subscribed to the service.
It took me about a week to realise they had been right.... the diapers STANK! a LOT! They were hard to put on, and subsequently I got to deal with soiled bedlinnen and cloting. My DD kept crying during diaperchanges (no I did not put a pin in her), cried as soon as she had soiled her diaper, and thus would not sleep through the night at all. I switched to disposables within a month and never regretted switching.
You do not want to hear you are wrong right now, and I am not going to tell you that you are. But please, leave some room for the reality that you may be wrong....
